Hey folks,
Sorry, I'm not subbed to the list, please keep me CC'd on replies.
What's the status on fixing xhci for Intel Lynx Point USB cores? I have several
boards with PCHs with this chipset in my lab that have no functional USB if
XHCI is enabled in BIOS on -CURRENT with all of the currently committed USB
changes. Is there anything I can do to help debug this problem? I found PR
179342 but it seems the issues there are resolved -- would going through the
debug procedure there be useful?
Hi,
Is the problem fixed if you set:
hw.usb.xhci.xhci_port_route=-1
in /boot/loader.conf
The board I am using for testing is:
SuperMicro X10SLM-F -- C226 chipset
I can make this available remotely for testing if needed.
Basically dmesg would do at first.
I also have another board with USB issues -- (dis)connects are not handled
after boot and the IPMI virtual devices don't attach properly, though USB
keyboard works as long as you don't disconnect it:
SuperMicro X9SBAA-F -- Atom S1260 SoC
XHCI is a more high-level controller, and I suspect that the makers have
added some propritary glue to switch ports back and forth between XHCI
and EHCI which is not documented anywhere.
--HPS
Thanks very much for any information you can provide.
